Early Holley Carb.?
I have an Holley carb. that I am going to restore and after I broke it down I found that instead of having a removable secondary well, it has one that is machined into the casting. The inside dia. looks to be the same as the removable, smooth and no threads. I saw this after sandblasting. Could this be an early one? has H on top and bottom with no letters on bottom front side of bowl .
Thanks, JD |

Bratton's sell a reproduction double venturi. If you look on the side you should see a boss where a pin was inserted to keep the venturi from rotating. Someone has probably ground the pin off to allow the single venturi to fit. I have a similar one and had a friend drill out the old pin, make a new one, and insert it. I installed one of Bratton's double venturi's and the carburetor performs well. Tom Endy |
